[0008] Furthermore, the filtration unit includes a drive assembly installed inside the housing for providing power; and a filter assembly disposed between the drive assembly and the collection unit; wherein the drive assembly is used to drive the filter assembly to shake, causing particles attached to the filter assembly to fall off.

[0010] Furthermore, the drive assembly includes a hinge block 1 fixedly connected to the inner wall of the top of the housing. A fixing ring is hinged to the bottom of the hinge block 1. A motor is fixedly connected to the inner wall of the fixing ring. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling.

[0016] 1. By setting up a filter section, when it is necessary to filter the tail gas of the methanol intermediate tank, the staff can first set the air inlet pipe at the tail gas outlet of the methanol intermediate tank, and then start the motor. The motor drives the eccentric wheel to rotate through the shaft. When the eccentric wheel rotates, it will shake. Under the connection of the hinge block two, the filter plate also begins to shake. At this time, several springs pull the filter plate. Then, the staff opens the valve, and the tail gas flows through the hose through the filter plate. Under the shaking of the filter plate, the particles attached to the filter plate will fall into the storage tank, thereby causing the filter plate to shake. This prevents the particles from accumulating on the surface of the filter plate or embedding in the filter holes during the process of filtering the tail gas. This not only extends the service life of the filter plate, but also reduces the frequency of manual disassembly and cleaning due to filter hole blockage.

[0017] 2. By setting up a collection section, after the filtration process is completed, the operator can pull two levers. At this time, the two limiting blocks move away from each other, the two springs are compressed, and the two limiting blocks stop limiting the limiting ring. The operator can then remove the storage tank to process the collected particles. Afterward, the operator releases the two levers, and the levers return to their original position under the elastic action of the two springs. After the storage tank is cleaned, the operator can pull the two levers again, aligning the top of the storage tank with the bottom of the housing and pushing it in. After pushing it in, the operator releases the two levers, and the two limiting blocks again limit the limiting ring, preventing the storage tank from falling off. This allows the particles to be collected, preventing secondary pollution of the filtered exhaust gas. Simultaneously, pulling the levers allows the storage tank to be removed, facilitating regular cleaning of particle deposits and effectively improving work efficiency.
